moeaarnrcar. onet me-Macrame Be itknown that l[, EDWIN W. PIERSON, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Typographical Casting-Machines, of which the following is a specification, reference being bad therein to the accompanying drawing.

My invention relates to typographical casting machines, such as linotype machines of the general organization represented. in Letters Patent of the United States, No. 436532, to O. Mergenthaler, wherein circulating matrices are released from a maga zine 1n the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through a distributing mechanism to the magazine from which they started. More particularly, it relates to the means for presenting the composed line to the; mold, and is designed to vary automatically 1 the extent of the presenting movement as;

nection therewith; Fig. 3 is .a transverse In machines of the class described, and particularly in linotype machines, it is customary to employ a plurality of molds of different molds are called into service.

diflt'erent dimensions, according to the character of the slug to be cast therein, as forexample, where the machine is equipped to produce either slugs having ordinary letters, or slugs having head letters, as may be desired. The characters on the headletter matrices are of considerably greater size than those on the ordinary matrices, and the respective mold slots vary correspondingly in width, and moreover, the po sitions of the characters on the'respective, matrices are difierent. These differences in 1 arrangement necess tate the arrest of the first elevator or presenting means in different relative positions to the several molds, so as to efi'ect the proper registration therewith of the composed lines of matrices. This result has been previously efiected in various ways not necessary here to detail at length.

It is the purpose of my present invention to accomplish the desired object automatically by the mechanical selectlon of the Sp(animation of fietters Patent. Application filed June 13, 1913. Serial No. 773,474.

mold, and more specifically, by means con- ,nected to the rotary mold carrier which act to interpose or withdraw the necessary stop, when the carrier is turned to bring a new mold into operative position.

In the accompanying drawings, I have shownmy invention in preferred form and by way of example, and as applied to a lmotype machine, but many changes and variations may be made therein, and in its mode of adaptation, which will be comprised within its spirit. Also, it may be applied to other forms of typographical casting machines, such as produce type or d1es, 1nstead of printing bars or'slugs as here n presented. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims,

in the accompanying drawings: Figure it is a perspective view, partly in section, of the first elevator, the mold wheel, and the vise frame, with my invention applied thereto; Fig. 2 is a transverse section, on

of the respective matrices employed in consectional-view through the first elevator and vise frame; and Fig. 4 is a view similar to Fig. 1, but showing the parts in different position.

'machine, or as illustrated in the Letters iPatent previously mentioned, the line composed of matrices X, or of matrices X, is lowered by the first elevator A into cast- .ing position between the jaws E and E mounted upon the vise frame F, and so as I), carried by the rotary mold wheel or carrier B The line is then justified, the mold wheel B advances to engage the mold therewith, and molten metal is injected into the mold, all in the usual manner. The parts so far described are or may be of any well-known or appropriate character, such as are illustrated in the before-mentioned Letters Patent or employed in the ordinary linotype machine, and their special construc tion and arrangement constitute no part of my present'invention.

In the form illustrated, two molds C and D, are shown asmounted'in the wheel B.

an enlarged scale, of two molds of different zdimenslons, and showing also edge views Y As is customary in the ordinary linotype to register it with the mold C, or the mold The mold C is of the usual dimensions and is designed to, cooperate with the ordinary matrices X. The mold D -is formed with a larger mold slot and is intended to cooperate with the head-letter matrices X. It will be noted that the characters in the matrices X are not only larger than those in the matrices X, but in addition are differently'located thereon, and that the size and location of the slots in the molds C and D correspondingly differ. It therefore becomes necessary to arrest the elevator A in different relative position to the mold wheel B, according to whether the mold C and matrices X. or the mold-Band matrices X, are in operation.

The extent of movement of the elevator A is normally controlled by the contact of the screw G with the vise frame F, and the necessary actuation of' the rod J, frequently termed the automatic, is eifected by the screw H. The rod J corresponds to the rod indicated by the letter of reference (1. in the aforesaid Mergenthaler patent, and its mode of operation is well understood by those skilled in the art.

In Fig. 4, the parts are shown with the mold C in casting position, at which time the elevator A descends until it is arrested by the contact of the screw G with the vise frame F, when the rod J is moved by. the screw H. This may be regarded as the regular or ordinary operation of the mechanism. When it is desired to employ a mold and matrices of different character, such as the mold D in connection with the head-letter matrices X, the mold wheel B is swung about its axis until the parts assume the position indicated in Figs. 1 and 3. It is now necessary that the elevator A be arrested at a higher point, and this is effected by the movement of the interponent K into position between the screw G and the vise frame F, and in order that the screw H may still actuate the rod J, by the similar shifting of the interponent L over the top of the rod. The interponent K is shown as connected to the pivoted lever K mounted upon the vise frame F, and the interponent L as connected to the spring arm L connected to the lever K, so that the two'interponents may be moved together into and out of operative position. Also pivotally mounted upon the vise-frame F is the elbow lever M connected at one end to the lever K, and provided with the spring M which normally .holds it in engagement with the stop pin M so that the parts occupy the positions shown in Fig. 4. The other arm of the lever M projects outwardlyfrom the vise frame Fin osition to be acted upon by one end of the ever N pivoted at N to the main frame. The mold wheel B is provided with the abutment 0, mounted thereon in such relation to the mold D, that when the latter is brought into the casting position, the abutment acts upon the other end of the lever N and swings it about its pivot. This movement of the lever N acting through the levers M and K, shifts the interponents K and L (Figs. 1 and 3) into operative position so as to arrest the elevator A at a higher point and still insure the actuation of the rod J, as previously described. When it is desired to resume the employment of the mold C, and the mold wheel B is turned for that purpose, the abutment O is swung out of engagement with the lever N, and the spring M restores the interponents K and L, to inoperative position as shown in Fig. 4. It will thus be seen that the mechanical selection of the mold automatically adjusts the arresting means for the elevator, and that the operator is entirely relieved from the care and attention otherwise necessary, thereby minimizing the liability to maladjustment or disarrangement of the parts, and the disadvantages resulting therefrom. The outer end of the projecting arm of the elbow lever M is beveled as at M to permit and insure its free passage with relation to the end of the lever N, as for instance when the vise frame F is swung outwardly and then inwardly, as sometimes occurs in the employment of the machine.

As previously stated, I have shown my invention only in preferred form and by Way of example, and as applied to a linotype machineybut obviously many alterations and modifications therein and in its mode of adaptation will suggest themselves to those skilled in the art, without departure from its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

1. In a typographical castin machine, the combination of a. plurality o molds capable, of independent use, a matrix carrier movable to different extents to correspond to one or another of the molds in use, and automatic means to determine theextent of movement of the carrier.

2. In a typographical casting machine, the combination of a plurality of molds capable of independent use, a matrix carrier movable to different extents to correspond to one or another of the molds in use, and means whereby the mechanical selection of a mold automatically varies the extent of movement of the carrier to correspond therewith.

3. In a typographical casting machine, the combination of a plurality of molds, a. matrix-presenting device, and means for bringing any selected mold into action and simultaneously varying the relation of the presenting device thereto.

4. In a typographical castin machine, the combination of a plurality o interchangeable molds, a matrix carrier movable to different extents, and means whereby an interchange of molds effects a change in the extent of movement of the carrier.

5. In a typographical casting machine, the combination of a mold carrier movable to bring a selected mold into action, a matrixpresenting device movable to difi'erent extents, and adjustable means controlled in their adjustment by the movement of the mold carrier to vary the extent of movement of said presenting device.

6. In a typographical casting machine, the combination of a plurality of movable molds, a movable matrix carrier, and adjustable means for arresting the matrix carrier in different positions, the said means being controlled in their adjustment by the movement of the molds.
